Dura Ace Track Stages Power Meter Install

Dura Ace Track Stages Power Meter Install

Power meter options for track bikes are very limited, and the Dura Ace Stages power meter is one of the most reasonably priced and simple to use on the market.  Based on the Dura Ace 7710 Octalink platform, the Stages power meter offers a simple, elegant power measuring solution for fixed gear bikes.  Painstaking refinement has gone into the algorithm used to calculate power to meet the unique demands of a fixed gear bike, improving performance and reliability in data recording.

Check out the video of the installation, re-posted from Periscope.  Throughout the installation, there's a little bit of Q&A about power meters based on questions from live viewers.  Click through the jump to watch the video and check out the video show notes:

If you're in the market for a power meter, I recommend Stages and they're huge supporters of the Tailwind Cocaching Podcast, so check them out.  Like all Stages Power Meters, the Dura Ace 7710 track model is sold as a left crank arm with an electronics pod mounted to it.  The same CR2032 battery that powers every Stages power meter supplies the power for this unit as well, making it user-friendly and easy to replace.

Stages Power Meter Install Q&A:

Q: What is a power meter and how does it work?

A power meter is a tool that measures the amount of effort that's going into your pedals.

Pretty simply, a power meter is a device that contains a series of strain gauges and measures the force put through the crank arm.  In the case of a Stages power meter, there's a pod mounted to the back of the left crank arm.  That pod contains strain gauges, which change electrical properties based on the deformation of the crank arm when it's put under load (your pedaling.)  That change in electrical properties can be interpreted, through an algorithm, as the amount of force needed to deform the crank arm.  Combine it with an accelerometer based cadence measurement and you can calculate power.

Q: What is power?

Power is a combination of pedal force and pedaling cadence.  It is an absolute measure of effort, expressed in watts.  Power is a useful metric to track because it is independent of daily physiological variability.  Heart rate is a much cheaper option (more on that below) to start tracking, but it can vary based on physiological status each day.  Power itself is a measure of output (how much force goes into the pedals) vs a measure of input (how hard my body is working to put that force to the pedals.)

For example, if I'm putting out 200 Watts of power, I'm putting out 200 Watts of power.  Today I may be doing that 200 W at a heart rate of 150 Beats Per Minute.  Tomorrow I may drink 4 cups of coffee before I ride, sleep poorly the night before and be stressed out, and I'll put out 200 W of power at 170BPM.

The output doesn't change, but how hard the body works to make that output happen changes quite a bit.  That's what makes a power meter a great training tool: you have absolute data to work with.

Q: How much does a power meter cost?

Power meters can vary greatly in price.  A Stages Power Meter such as the Dura Ace 7710 that I install in the video runs about $650 USD.  Some other examples, such as SRMs run around $2500 USD.  Each kind of power meter has its own advantages and disadvantages, and you can read about each one of them in my “Choosing A Power Meter” post/podcast.

About the Author:

After graduating from Ithaca College with a degree in Exercise and Sport Science/Pharmacology, I continued my education with a doctorate of Chiropractic from New York Chiropractic College. As I progressed through my education, I was able to apply the concepts I learned in the lab to my own daily workouts and goals. At the time, I was following some of the principles of traditional coaching and getting mediocre results. Frustrated, I realized that if I could apply all my physiology, chemistry, nutrition and training knowledge, I could “build a better mousetrap” not just for my own training, but for other athletes. With this goal in mind, I started Tailwind Coaching, to help cyclists [with busy lives and limited training time] become stronger, faster, fitter and healthier. And while I may not be a ex-ProTour rider, an Olympic Coach or even a prolific race winner, I am something that most coaches are not: a regular guy just like you who has a job, a family and a desire to be a stronger cyclist.
